Abstract
The utility model discloses it is a kind of based on imporosity filling multilayered structure PTFE ball valve sealing ring, be related to the sealing ring applied technical field of ball valve, including for pure PTFE material carrier layer, be the glue layer of resin material and be imporosity PTFE material protective layer.Beneficial effect is: protective layer is imporosity PTFE layers compared with pure PTFE, and the porosity of imporosity PTFE provided by the utility model is greatly reduced, and has superior sealing performance.PTFE ball valve sealing ring concave side in imporosity provided by the utility model is designed as carrier layer; the three-decker of carrier layer, glue layer and protective layer can not only largely control the production cost of product, and ensure that the sealing performance of PTFE ball valve sealing ring in imporosity provided by the utility model.
Description
Technical field
The utility model relate to ball valve sealing ring applied technical field more particularly to it is a kind of based on imporosity filling it is more
Layer structure PTFE ball valve sealing ring.
Background technique
Currently, most commonly used ball valve sealing ring is all made of PTFE material in the market, PTFE is referred to as " King ",
This material has antiacid alkali resistant, resists various organic solvents, the excellent characteristic such as performance stabilization, therefore be readily applicable to make sealing ring
Field in.
And PTFE ball valve sealing ring in the market has that porosity is big, and mechanical strength is low mostly, rub resistance, impervious not poor
The disadvantages of, these factors all limit further development of the PTFE in sealing ring field to a certain extent.
Utility model content
The purpose of this utility model is to provide for a kind of multilayered structure PTFE ball valve sealing ring based on imporosity filling.
The utility model is that technical solution used by solving its technical problem is: a kind of multilayer based on imporosity filling
Structure PTFE ball valve sealing ring, including carrier layer, glue layer and protective layer, the protective layer are pressed together on carrier layer by glue layer
On, the carrier layer is pure PTFE, and the glue layer is resin, and the protective layer is imporosity PTFE.
Preferably, the carrier layer is ball valve sealing ring concave side.
Preferably, the glue layer with a thickness of 7~15um.
Preferably, the protective layer with a thickness of 50~200um.
Preferably, the imporosity PTFE film of the protective layer carried out how sodium is handled.
Utility model has the advantages that
1, protective layer is imporosity PTFE layers, and compared with pure PTFE, the porosity of imporosity PTFE is greatly reduced, and is had
Superior sealing performance.
2, ball valve sealing ring concave side provided by the utility model is designed as carrier layer, carrier layer, glue layer and protective layer
Three-decker can not only largely control the production cost of product, and ensure that imporosity PTFE ball valve sealing ring
Sealing performance.

Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines diagram and specific embodiment, and the utility model is further described.
Embodiment
As shown in Figure 1, the utility model proposes it is a kind of based on imporosity filling multilayered structure PTFE ball valve sealing ring,
Including carrier layer 1, glue layer 2 and protective layer 3, protective layer 3 is pressed together in carrier layer 1 by glue layer 2, and carrier layer 1 is pure
PTFE, glue layer 2 are resin, and protective layer 3 is imporosity PTFE, and the carrier layer 1 of pure PTFE material has antiacid alkali resistant, resists
The characteristics of various organic solvents, is that the first glue layer 2 of resin glue material has the characteristics of waterproof, oil resistant, strong alkali-acid resistance, is
3 porosity of protective layer of imporosity PTFE is greatly reduced, and has superior sealing performance.
Further, carrier layer 1 is ball valve sealing ring concave side.
Further, glue layer 2 with a thickness of 7~15um.
Further, protective layer 3 with a thickness of 50~200um.
Further, the imporosity PTFE film of protective layer 3 carried out how sodium is handled.
When the utility model is used, being mixed first: by polytetrafluoroethylene (PTFE), glass and imporosity additive are pressed
It is poured into according to certain ratio and carries out uniform stirring in mixing machine, be pressed and molded: uniformly mixed mixture is added to the mould of mold
It is intracavitary, it is 50MPa in pressure, preforming process is carried out under the condition of molding that temperature is 23-28 DEG C, the dwell time is 5min left
Sintering: preformed blank is put into sintering furnace and heated, be polymerized to ptfe composite self-solidifying by heat transfer by the right side
Certain shapes finished product, the temperature general control of sintering furnace at 300 DEG C -370 DEG C, soaking time general control in 10h or so, rise,
Rate of temperature fall general control is at 70 DEG C/h-90 DEG C, machining: the finished product sintered is carried out according to required specification and size
Machining obtains required imporosity PTFE film, and how sodium is handled: imporosity PTFE film is carried out how sodium processing improves its table
Coating processing: face activation will have been coated with the pure PTFE ball valve sealing ring of glue layer by how the PTFE film of sodium processing is plated in
Surface.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, the utility model can also on the premise of not departing from the spirit and scope of the utility model
There are various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The utility model is wanted
Protection scope is asked to be defined by appended claims and its equivalent.
